Answer:
Step 1: Multiply the entire first equation by 2.
Step 2: Rewrite the system of equations, replacing the first equation with the new equation.
Step 3: Add the equations.
Step 4: Solve for x.
Step 5: Find the y-value by substituting in 3 for x in either equation.
Step 6: Identify the solution as an ordered pair.
5 is not a divisor of any of the dimensions of the given box, so selections A, C, D can't work.
Each of the dimensions of selection B is a divisor of a different dimension of the box, so ...
.. the correct choice is selection B) 7 × 9 × 12.

<u>Kenny</u>
<em>See attachment for complete question</em>
Required
Determine the amount for 2x and 3y
From Jamal's and Kenny's orders we have:
--- (1)
--- (2)
Multiply (1) by 3
![3 * [3x + 2y = 4.85]](https://tex.z-dn.net/?f=3%20%2A%20%5B3x%20%2B%202y%20%3D%204.85%5D)
--- (3)
Subtract (2) and (3)
Solve for x
Substitute in
Solve for y
So, the cost of 2x and 3y is:
Answer:
0.375
Step-by-step explanation:
You have to just divide 3/4 divided by 2 = 0.375
